If the material or process specified or required by Owner is an infringement, the Contractor shall be responsible for such loss unless he promptly gives written notice to the Owner of such infringement. 32. LAWS AND ORDINANCES The Contractor shall at all times observe and comply with all federal, state and local laws, ordinances and regulations, which in any manner effect the contract or the work, and shall indemnify and save harmless the Owner against any claims w l arising from the violation of any such laws, ordinances, and regulations, whether by the Contractor or his employees.

The Contractor further agrees that subletting of any portion or feature of the work, or materials required in the performance of this contract, shall not relieve the Contractor from his full obligations to the Owner, as provided by this contractual agreement. 34. TIME FOR COMPLETION AND LIQUIDATED DAMAGES �-- It is hereby understood and mutually agreed by and between the Contractor and the Owner, that the date of beginning and time for completion as specified in the contract of work to be done hereunder are essential conditions of this contract; and it is further mutually understood and agreed that the work embraced in this contract shall be commenced on a date to be specified in the Notice to Proceed. If the Contractor should neglect, fail, or refuse to complete the work within the time herein specified, or any proper extension thereof granted by the Owner, then the Contractor does hereby agree as part of the consideration for the awarding of this contract, the Owner may withhold permanently from Contractor's total compensation, the sum of $200.00 (Two Hundred) PER DAY, not as a penalty, but as liquidated damages for the breach of the contract as herein set forth for each and every calendar day that the Contractor shall be in default after the time stipulated for completing the work. It is expressly understood and agreed, by and between Contractor and the Owner, that the time for the completion of the work described herein is reasonable time for the completion of the same, taking into consideration the average climatic change and conditions and usual industrial conditions prevailing in this locality. The amount is fixed and agreed upon by and between the Contractor and the Owner because of the impracticability and extreme difficulty in fixing and ascertaining actual damages the Owner would in such event sustain, and the amount is agreed to be damages the Owner would sustain and shall be retained by the Owner from current periodical estimates for payments or from final payment. It is further agreed and understood between the Contractor and Owner that time is of the essence of this contract. 35. TM E AND ORDER OF COMPLETION It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the Contractor shall be allowed to prosecute his work at such time and sessions, in such order of precedence, and in such manner as shall be most conductive to economy of construction; provided, however, that the order and time of prosecution shall be such that the r• work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and specifications, and within the time of completion designated in the proposals; provided, also, that when the Owner is having other work done, either by contract or by his own force, the Owner's Representative may direct the time and manner of constructing r i work done under this contract so that conflicts will be avoided and the construction of the various works being done for the Owner shall be harmonized. The Contractor shall submit, at such times as may reasonably be requested by the Owner's Representative, schedules which shall show the order in which the Contractor proposes to carry on the work, with dates at which the Contractor will start the several parts of the work and estimated dates of completion of the several parts. 36. EXTENSION OF TIME The Contractor agrees that he has submitted his proposal in full recognition of the time required for the completion of this project, taking into consideration the average climatic range and industrial conditions prevailing in this locality, and has considered the liquidated damage provisions of paragraph 33 hereinabove setforth and that he shall not be entitled to, nor will he request, an extension of time on this contract, except when his work has been delayed by an act or neglect of the Owner, Owner's Representative, employees of the Owner or other contractors employed by the owner, or by changes ordered in the work, or by strike, walkouts, acts of God or the public enemy, fire or flood. The Contractor may apply in writing for an extension of time, submitting therewith all written justification as may be required by Owner's Representative for such an extension as requested by Contractor. The Owner's Representative within ten (10) days after receipt of a written request for an extension of time by the Contractor supported by all requested documentation shall then submit such written request to the City Council of the City of Lubbock for their consideration. Should the Contractor disagree with the action of City Council on granting an extension of time, such disagreement shall be settled by arbitration as hereinafter provided. 37. HINDRANCE AND DELAYS In executing the contract agreement, the Contractor agrees that in undertaking to complete the work within the time herein fixed, he has taken into consideration and made allowances for all hindrances and delays incident to such work, whether growing out of delays in securing material or workmen or otherwise. No charge shall be made by the Contractor for hindrance or delays from any cause during the progress of any part of the work embraced in this contract except where the work is stopped by order of the Owner or Owner's Representative for the Owner's convenience, in which event, such expense as in the judgment of the Owner's Representative that is caused by such stoppage shall be paid by Owner to Contractor. 38. QUANTITIES AND MEASUREMENTS No extra or customary measurements of any kind will be allowed, but the actual measured or computed length, area, solid contents, number and weight only shall be considered, unless otherwise specifically provided.In the event this contract is let on a unit price basis, then Owner and Contractor agree that this contract, including the specifications, plans and other contract documents are intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing their proposals offered for the work. It is understood and agreed that the actual amount of work to be done and the materials to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of work done and materials furnished on the project. 39. PROTECTION OF ADJOINING PROPERTY The Contractor shall take proper means to protect the adjacent or adjoining property or properties in any way encountered, which may be injured or seriously affected by any process of construction to be undertaken under this agreement, from any damage or injury by reason of said process of construction; and he shall be liable for any and all claims for such damage on account of his failure to fully protect all adjacent property. The Contractor agrees to indemnify, save and hold harmless the Owner against any claim or claims for damages due to any injury to any adjacent or adjoining property, arising or growing out of the performance of this contract, but such indemnity shall not apply to any claim of any kind arising out of the existence or character of the work. PIK t 40. PRICE FOR WORK In consideration of the furnishing of all necessary labor, equipment and material and the completion of all work by the Contractor, and on the delivery of all materials embraced in this contract in full conformity with the specifications and stipulations herein contained, the Owner agrees to pay the Contractor the price set forth in the proposal attached hereto, which has been made a part of this contract, and the Contractor hereby agrees to receive such price in full for furnishing all materials and all labor required for the aforesaid work, also, for all expenses incurred by him and for well and truly performing the same and the whole thereof in the manner and according to this agreement, the attached specifications, plans, contract documents and requirements of Owner's Representative. 41. PAYMENTS No payments made or certificates given shall be considered as conclusive evidence of the performance of the contract, either wholly or in part, nor shall any certificate or payment be considered as acceptance of defective work. Contractor shall at any time requested during the progress of the work furnish the Owner or Owner's Representative with a verifying certificate showing the Contractor's total outstanding indebtedness in connection with the work. Before final payment is made, !" Contractor shall satisfy Owner, by affidavit or otherwise, that there are no outstanding liens against Owner's premises by reason of any work under the contract. Acceptance by Contractor of final payment of the contract price shall constitute a waiver of all claims against Owner which have not theretofore been timely filed as provided in this contract. 42. PARTIAL PAYMENTS On or before the tenth day of each month, the Contractor shall submit to Owner's Representative an application for partial payment. Owner's Representative shall review said application for partial payment and the progress of the work made by the Contractor and if found to be in order shall prepare a certificate for partial payment showing as completely as practical the total value of the work done by the Contractor up to and including the last day of the preceding month; said statement shall also include the value of all sound materials delivered on site of the work that are to be fabricated into the work The Owner shall then pay the Contractor on or before the fifteenth day of the current month the total amount of the Owner's Representative's Certificate of Partial Payment, less S% of the amount thereof, which S% shall be retained until final payment, and further, less all previous payments and all further sums that may be retained by Owner under the terms of this agreement. It is understood, however, that in case the whole work be near to completion, and this fact is certified to by Owner's Representative and some unexpected and some unusual delay occurs due to no fault or negligence on the part of the Contractor, the Owner may upon written recommendation of Owner's Representative pay a reasonable and equitable portion of the retained percentage due Contractor. 43. FINAL COMPLETION AND ACCEPTANCE Within thirty-one (31) days after the Contractor has given the Owner's Representative written notice that the work has been completed or substantially completed, the Owner's Representative and the Owner shall inspect the work and within said r" time, if the work be found to be completed or substantially completed in accordance with the contract documents, the Owner's Representative shall issue to the Owner and Contractor his certificate of completion, and thereupon it shall be the duty of the Owner within thirty-one (31) days to issue a certificate of acceptance of the work to the Contractor. 44. FINAL PAYMENT , Upon the issuance of the certificate of completion, the Owner's Representative shall proceed to make final measurement and prepare a final statement of the value of all work performed and materials furnished under the terms of the agreement, and shall certify same to the Owner, who shall pay to the Contractor on or before the 31 st day after the date of certificate of completion, the balance due Contractor under the terms of this agreement, provided he has fully performed his contractual obligations under the terms of this contract; and said payment shall become due in any event upon said performance by the Contractor. Neither the certificate of acceptance nor the final payment, nor any provisions in the contract documents shall relieve the Contractor of the obligation for fulfillment of any warranty which may be required in the special conditions (if any) of this contract or required in the specifications made a part of this contracL I 45. CORRECTION OF WORK BEFORE FINAL PAYMENT FOR WORK Contractor shall promptly remove from Owners' premises all materials condemned by the Owner's Representative on account of failure to conform to the contract, whether actually incorporated in the work or not, and Contractor shall at his own expense promptly replace such condemned materials with other materials conforming to the requirements of the contract. Contractor shall also bear the expense of restoring all work of other contractors damaged by any such removal or replacement. If Contractor does not remove and replace any such condemned work within a reasonable time after a written notice by the Owner or the Owner's Representative, Owner may remove and replace it at Contractor's expense. 46. CORRECTION OF WORK AFTER FINAL PAYMENT Neither the final payment nor certificate nor any provision in this contract shall relieve the Contractor of responsibility for faulty materials or workmanship, and he shall remedy any defects due thereto and pay for any damage to other work resulting therefrom, which shall appear within a period of one (1) year from the date of substantial completion. The Owner or the Owner's Representative shall give notice of observed defects with reasonable promptness. 47. - PAYMENT WI WMLD The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect himself from loss on account of. (a) Defective work not remedied. (b) Claims filed or reasonable evidence indicating possible filing of claims. (c) Failure of the Contractor to make payments promptly to subcontractors or for materials or labor. (d) Damage to another contractor. When the above grounds are removed, or the Contractor provides a surety bond satisfactory to the Owner, which will protect the Owner in the amount withheld, payment shall be made for amounts withheld because of them. 48. TIME OF FILING CLAIMS It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in writing and filed with the Owner's Representative within fifteen (15) days after the Owner's Representative has given any directions, order or instruction to which the Contractor desires to take exception. The Owners' Representative shall reply to such written exceptions by the Contractor and render his final decision in writing. In case the Contractor should appeal from the decision of the Owner's Representative, any demand for arbitration shall be filed with the Owner's Representative and the Owner in writing within ten (10) days after the date of delivery to Contractor of the final decision of the Owner's Representative. It is further agreed that final acceptance of the work by the Owner and the acceptance by the Contractor of the final payment shall be a bar to any claim by either party, except where noted otherwise in the contract documents. 49. ARBITRATION All questions of dispute under this agreement shall be submitted to arbitration at the request of either party to the dispute. The parties may agree upon one arbitrator, otherwise, there shall be three; one named in writing by each party and the third chosen by the two arbiters selected; or if the arbiters fail to select a third within ten (10) days, he shall be chosen by the District Judge, 72nd Judicial District of Texas. Each arbiter shall be a resident of the City of Lubbock. Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the decision of the Owner's Representative shall be final and binding on him. Should the other party fail to choose an arbiter within ten (10) days, the Owner's Representative shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are empowered by both parties to take Ex Parte Proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract, unless either or both parties shall appeal within ten (10) days from date of the award by the arbiters, and it is hereby agreed that i r* r each party shall have the right of appeal and all proceedings shall be according to and governed by Arbitration Statutes of Texas, being Article 224, et seq., Vernon's Annotated Civil Statutes. THE DECISION OF THE ARBITERS UPON ANY r" QUESTION SUBMITTED TO ARBITRATION UNDER THIS CONTRACT SHALL BE A CONDITION PRECEDENT TO ANY RIGHT OF LEGAL ACTION. The arbiters, if they deem the rase demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and if the appeal was taken without reasonable cause, they may award damages for any delay occasioned thereby. The arbiters shall fix their own compensation, unless otherwise provided by agreement, and shall assess the costs and charges of the arbitration upon either or both parties. The award of the arbiters must be made in writing and shall not be open to objection on account of the form of proceedings or award 50. ABANDONMENT BY CONTRACTOR ' In rase the Contractor should abandon and fail or refuse to resume work within ten (10) days after written notification from the Owner or the Owner's Representative, or if the Contractor fails to comply with the orders of the Owner's Representative, �.. when such orders are consistent with this contract, this Agreement, or the Specifications hereto attached, then the Surety on s the bond shall be notified in writing and directed to complete the work and a copy of said notice shall be delivered to the ` Contractor. r After receiving said notice of abandonment, the Contractor shall not remove from the work any machinery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under the contract for work, may be held for use on the work by the Owner or the Surety of the Contractor, or another contractor, in completion of r the work; and the Contractor shall not receive any rental or credit therefore (except when used in connection with Extra Work, where credit shall be allowed as provided for under paragraph 24 of this contract); it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. In case the Surety should fail to commence compliance with the notice for completion hereinbefore provided for within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: (a) The Owner may employ such force of men and use of machinery, equipment, tools, materials and supplies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said Contractor, and the expense so charged shall be deducted and paid by the Owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, if the same had been completed by the Contractor, then said Contractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said Contractor, then the Contractor and/or his Surety shall pay the amount of such excess to the Owner, or (b) The Owner, under scaled bids, after notice published as required by law, at least twice in a newspaper having a general circulation in the County of location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case of any increase in cost to the Owner under the new contract as compared to what would have been the cost under this contract, such increase shall be charged to the Contractor and the Surety shall be and remain bound therefore. However, should the cost to complete any such new contract prove to be less than that which would have been the cost to complete the work under this contract, the Contractor or his Surety shall be credited therewith When the work shall have been substantially completed, the Contractor and his Surety shall be so notified and certificates of r- completion and acceptance, as provided in paragraph 42 hereinabove set forth, shall be issued. A complete itemized statement of the contract accounts, certified to by Owner's Representative as being correct shall then be prepared and delivered to Contractor and his Surety, whereon the Contractor or his Surety, or the Owner as the case may be, shall pay the C• balance due as reflected by said statement within 30 days after the date of certificate of completion. In the event the statement of accounts shows that the cost to complete the work is less than that which would have been the cost to the Owner had the work been completed by the Contractor under the terms of this contract, or when the Contractor and/or his Surety shall pay the balance shown to be due by them to the Owner, then all machinery, equipment, tools, materials or supplies left on the site of the work shall be turned over to the Contractor and/or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor and/or his Surety fail to pay the amount due the Owner within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials shall be mailed to the Contractor and his Surety at the respective addresses designated in this contract; provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shalt be held at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any machinery, equipment, tools, materials, or supplies which remain on the'*jobsite and belong to persons other than the Contractor or his Surety, to their proper owners. 51. ABANDONMENT BY OWNER In case the Owner shall fail to comply with the terms of this contract, and should fail or refuse to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, tools, and equipment, and all materials on the ground that have not been included in payments to the Contractor and have not been incorporated into the work. Thereupon, the Owner's Representative shall make an estimate of the total amount earned by the Contractor, which estimate shall include the value of all work actually completed by said Contractor at the prices stated in the the attached proposal, the value of all partially completed work at a fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Contractor to carry the whole work to completion, and which cannot be utilized. The Owner's Representative shall then make a final statement of the balance due the Contractor by deducting from the above estimate all previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this Agreement, and shall certify same to the Owner who shall pay to the Contractor on or before thirty (30) days after the date of the notification by the Contractor the balance shown by said final statement as due the Contractor, under the terms of this Agreement. 52. BONDS The successful bidder shall be required to furnish a performance bond and payment bond in accordance with Article 5160, Vernon's Annotated Civil Statutes in the amount of 100% of the total contract price, in the event said contract price exceeds $25,000.00. If the contract price does not exceed $25,000.00, the statutory bonds will not be required. All bonds, if required, shall be submitted on forms supplied by the Owner, and executed by an approved Surety Company authorized to do business in the State of Texas. And it is further agreed that this contract shall not be in effect until such bonds are so furnished. 53. SPECIAL CONDITIONS In the event special conditions are contained herein as part of the contract documents and said special conditions conflict with any of the general conditions contained in this contract, then in such event the special conditions shall control. 54. LOSSES FROM NATURAL CAUSES Unless otherwise specified herein, all loss or damage to the Contractor arising out of the nature of the work to be done, or from the action of the elements, or from any unforeseen circumstance and the prosecution of the same, or from unusual obstructions or difficulties which may be encountered in the prosecution of the work, shall be sustained and borne by the Contractor at his own cost and expense. 55. INDEPENDENT CONTRACTOR Contractor is, and shall remain, an independent contractor with full, complete and exclusive power and authority to direct, supervise, and control his own employees and to determine the method of the performance of the work covered hereby. The fact that the Owner or Owner's Representative shall have the right to observe Contractor's work during his performance and to carry out the other prerogatives which are expressly reserved to and vested in the Owner or Owner's Representative 56. hereunder, is not intended to and shall not at any time change or effect the status of the Contractor as an independent contractor with respect to either the Owner or Owner's Representative or to the Contractor's own employees or to any other person, 5rm, or corporation. CLEANING UP The Contractor shall at all times keep the premises free from accumulation of debris caused by the work, and at the completion of the work he shall remove all such debris and also his tools, scaffolding, and surplus materials and shall leave the work room clean or its equivalent. The work shall be left in good order and condition. In case of dispute Owner may remove the debris and charge the cost to the Contractor.

PART 3 EXECUTION 3.1 ANCHOR TRENCH The anchor trench shall be excavated to the line, grade, and width shown on the construction drawings, prior to liner system placement. The Engineer shall verify that the anchor trench has been constructed according to construction drawings. If the anchor trench is located in a clay susceptible to desiccation, no more than the amount of trench required for the base geomembrane to be anchored in one day shall be excavated to minimize desiccation of the anchor trench soils. 2687-94 02245 - 11 Slightly rounded corners shall be provided in the trench where the geomembrane adjoins the trench so as to avoid sharp bends in the geomembrane. 3.2 PLACEMENT A. The Installer shall be responsible for the following: • No equipment or tools shall damage the geomembrane by handling, trafficking, or other means. • No personnel working on the geomembrane shall smoke, wear damaging shoes, or engage in other activities that could damage the geomembrane. • The method used to unroll the panels shall not cause scratches or crimps in the geomembrane and shall not cause indentations in the supporting soil greater than one inch deep or damage to the underlying geotextile. • The method used to place the panels shall minimize wrinkles. Wrinkles shall be identified as to proper location and compensation shall be identified on the Contractor's and Engineer's drawings. Ballast shall be used to prevent relocation of the compensating wrinkles by wind. • Adequate loading (e.g., sand bags or similar items that will not damage the geomembrane) shall be placed to prevent uplift by wind (in case of high winds, continuous loading is recommended along edges of panels to minimize risk of wind flow under the panels). • Direct contact with. the geomembrane shall be minimized, i.e., the geomembrane in traffic areas is protected by geotextiles, extra geomembrane, or other suitable materials. B. Weather Limitations Geomembrane deployment shall proceed between ambient temperatures of 32•F to 104•F. Placement can proceed below 32•F only after it has been verified by the Engineer that the material can be seamed according to the specification. Below 40•F, preheat of the FML may be requited. Geomembrane placement shall not be done during any precipitation, in the presence of excessive moisture (e.g., fog, rain, dew) or in the presence of excessive winds, as determined by the installation supervisor. C. Factory Seam Quality Verifications The Engineer will require the Contractor to test up to as much as 20% of factory fusion welds (non-destructive air pressure test and/or vacuum test) in the field to verify factory test results. Additional testing at the Installer's expense will be required if failed tests are obtained in the field. 3.3 FIELD SEAMING Seams shall be oriented parallel to the line of maximum slope, i.e., oriented down, not across the slope. In corners and odd -shaped geometric locations, the number of field seams shall be minimized. 2687-94 - 02245 - 12 r No base T-seam shall be closer than 5 feet from the toe of the slope. Seams shall be aligned with the least possible number of wrinkles and r "fishmouths." If a fishmouth or wrinkle is found, it shall be relieved and cap -stripped. A. Seam Overlap Panels of geomembrane must have a finished overlap of a minimum of 4 inches for hot shoe fusion welding and 3 inches for extrusion welding, but in any event sufficient overlap shall be provided to allow peel tests to be performed on the seam. No solvent or adhesive may be used unless the product is approved by the Owners Representative. (Samples shall be submitted to the Design Engineer for testing and evaluation). The procedure used to temporarily bond adjacent panels together shall not damage the geomembrane; in particular, the temperature of hot air at the nozzle of any spot welding apparatus shall be controlled such that the geomembrane is not damaged. B. Seaming Equipment and Accessories Approved equipment for field seaming are hot shoe fusion welders and extrusion welders. 1. Hot Shoe Welder, 110 Volt, 10 Amps. 2.

Field Tensiometer, capable of performing seam and peel adhesion tests for quantitative testing on -site. C. Test Seams Field test seams shall be conducted on geomembrane liner to verify that seaming conditions are satisfactory. Test seams shall be conducted for each seamen at the beginning of each seaming period, at the Engineer's discretion, and at least once! each 4 hours, for each seaming apparatus used that day. All test seams shall be made at a location selected by the Engineer in the area of the seaming and in contact with the subgrade. The test seam samples shall be 10 feet long for hot shoe welding and 3 feet long for extrusion welding with the seam centered lengthwise. Specimens 1 inch wide shall be cut from each opposite end of the test seam by the Engineer. The Engineer shall r 2687-94 02245 - 13 i use a tensiometer provided by - the Installer to test these specimens for shear and peel. If a test seam fails to meet field seam specifications, the seaming apparatus and/or seamer shall not be accepted and shall not be used for seaming until the deficiencies are corrected and two consecutive successful full test seams are achieved. D. Non -Destructive Seam Testing The Installer shall non-destructively test all field seams over their full length. All test equipment, including but not limited to the following shall be furnished by the Installer: 1. Vacuum Box testing Equipment for testing single wedge fusion seams and extrusion seams shall be comprised of the following: • A vacuum box assembly consisting of a rigid housing, a transparent viewing window, a soft rubber gasket attached to the bottom, port hole or valve assembly, and a vacuum gauge. • A steel vacuum tank and pump assembly equipped with a pressure controller and pipe connections. • A rubber pressure/vacuum hose with fittings and connections. • A plastic bucket and wide paint brush. • A soapy solution. The following procedures shall be followed by the installer: • Excess sheet overlap shall be trimmed away. • Clean the window, gasket surfaces and check for leaks. • Energize the vacuum pump and reduce the tank pressure to approximately 3-5 psi. • Wet a strip of geomembrane approximately 12 inches by 48 inches (length of box) with the soapy solution. • Place the box over the wetted area and compress. • Close the bleed valve and open the vacuum valve. • Ensure that a leak tight seal is created. • For a period of approximately 15 seconds, examine the geomembrane through the viewing window for the presence of soap bubbles. • If no bubbles appear after 15 seconds, close the vacuum valve and open the bleed valve, move''the box over the next adjoining area with a minimum 3 inches overlap and repeat the process. • All areas where soap bubbles appear shall be marked and repaired and then retested. The following procedures shall apply to locations where seams cannot be non-destructively tested, as determined by the Engineer: • If the seam is accessible to testing equipment prior to final installation, the seam shall be non-destructively tested prior to final installation. 2687-94 02245 - 14 • If the seam cannot be tested prior to final installation, the seaming operations shall be observed by the Engineer for uniformity and completeness. 2. Air Pressure Testing (For Double Fusion Seam Only) The following procedures are applicable to those processes which produce a double seam with an enclosed space. Equipment for testing double fusion seams shall be comprised of the following: • An air pump equipped with pressure gauge capable of generating and sustaining a pressure between 25 and 30 psi and mounted on a cushion to protect the geomembrane . • A manometer equipped with a sharp hollow needle, or other approved pressure feed device. The following procedures shall be followed by the Installer: • Seal one end of the seam to be tested. • Insert needle or other approved pressure feed device through the sealed end of the channel created by the double wedge fusion weld. • Energize the air pump to verify the unobstructed passage of air through the channel. • Seal the other end of the channel. • Energize the air pump to a pressure between 25 and 30 psi, close valve, and sustain pressure: for approximately 5 minutes. • If loss of pressure exceeds 4 psi, or pressure does not stabilize, locate faulty area, repair and retest. • Remove needle or other approved pressure feed device and seal. E. Destructive Seam Testing The Installer shall provide the Engineer with a minimum of one destructive test sample per 500 feet of seam length from a location specified by the Engineer. The Installer shall not be informed in advance of the sample location. 1. Sampling Procedure In order to obtain test results prior to completion of liner installation, samples shall be cut by the Installer as the seaming progresses. A destructive test must be done for each welding machine used for seaming or repairs. Sampling times and locations shall be determined by the Engineer. The Engineer must witness the obtainment of all field test samples and the Installer shall mark all samples with their location roll and seam number. The Installer shall also record in written form the date, time, location, roll seam number, ambient temperatures, and pass or fail description. A copy of the information must be attached to each sample portion. All holes in the geomembrane resulting from obtaining the seam samples shall be immediately repaired. All patches shall be vacuum tested. r, 2. Size and Disposition of Samples I 2687-94 02245 - 15 r- i The samples shall be 12 inches wide by 36 inches long with the seam ,centered lengthwise. The sample shall be cut into two equal length pieces, and given to the Engineer. 3. Field Testing The Installer shall cut six 1-inch wide replicate specimens from his sample and these shall be tested by the Engineer. The Installer shall test two specimens (four when possible for testing both tracks on dual -track fusion welded seams) for peel strength. All tests to be witnessed by the Engineer. To be acceptable, both test specimens must pass. Any specimen that.fails through the weld or by adhesion at the weldsheet interface is a Non-FTB break and shall be considered a failure. 4. Independent Laboratory Testing The Engineer will package and ship all destructive seam samples to an independent testing Laboratory for determination and verification of all field shear and peel strengths. The test method and procedures to be used by the Independent Laboratory shall be the same used in field testing, where seam samples are 1 inch wide, and the grip separation rate is 2 ipm. Theminimumpassing criteria for independent laboratory testing are all three of the following: • All seam samples tested in the peel mode must fail in FTB. • At least four of five seam samples from each peel and shear determination must meet the minimum specified value. • The average value from all five seam samples from each peel and shear determination must meet the minimum specified value. The above criteria apply to both tracks from each dual -track fusion welded seam before it is considered as passing. ALL FAILED LAB TESTS WILL BE PAID FOR BY THE INSTALLER. 5. Archive Samples The Installer will package and ship the remaining samples to the Engineer for archival. The samples shall include information that indicates where the sample was taken. 6. Procedures for Destructive Test Failure The following procedures shall apply whenever a sample fails the field destructive test: • The installer shall cap strip the seam between the failed location and any passed test location. • The installer can retrace the welding path to an intermediate location (at a minimum of 10 feet from the location of the failed test), at the Engineer's discretion, and take a small sample for an additional field test. If this test passes, then the seam shall be cap stripped between that location and the original 2687-94 02245 - 16 PM ' i failed location. If the test fails, then the process is ' repeated. Over the length of seam failure, the Contractor shall r either cut out the old seam, reposition the panel and reseam, or add a cap strip, as required by the Engineer. • After reseaming or placement of the cap strip, additional destructive field test(s) shall be taken within the reseamed area. The reseamed sample shall be found acceptable if test results are approved by the Engineer. If test results are not acceptable, this process shall be repeated until the reseamed length is judged satisfactory by the Engineer. In the event that a sample fails a laboratory destructive test, then the above procedures shall be followed, considering laboratory tests exclusively. The Engineer will document all actions taken in conjunction with destructive test failures. F. Defects and Repairs All seams and non -seam areas of the geomembrane shall be inspected by the Engineer for defects, holes, blisters, undispersed raw materials, and any sign of contamination by foreign matter. Because light reflected by the geomembrane helps to detect defects, the surface of the geomembrane shall be clean at the time of inspection. The geomembrane surface shall be brushed, blown, or washed by the Installer if the amount of dust or mud inhibits inspection. The Engineer shall decide if cleaning of the geomembrane is needed to facilitate inspection. 1. Evaluation Each suspect location in seam and non -seam areas shall be non-destructively tested as appropriate in the presence of the Engineer. Each location that fails the non-destructive testing shall be marked by the Engineer, and repaired accordingly. 2. Repair Procedures • Defective seams shall be restarted/reseamed as described in these specifications. PM • Small holes shall be repaired by extrusion cap welding. If the hole is larger than 1/4 inch, it shall be patched. • Tears shall be repaired by patching. Where the tear is �» on a slope or an area of stress and has a sharp end it G must be rounded prior to patching. • Blisters, large holes, undispersed raw materials, and contamination by foreign matter shall be repaired by patches. • Surfaces of HDPE which are to be patched shall be abraded and cleaned no more than 15 minutes prior to the r repair.
